新型氢氧化镁阻燃剂的应用研究

STUDY ON THE APPLICATION OF THE NOVEL Mg(OH)_2 AS A FIRE RETARDANT

新型氢氧化镁阻燃剂,其晶体在<101>方向的微观内应变<3×10^(-3),<101>方向的晶粒尺寸>80nm,比表面积(BET)<20m^2/g,在与聚乙烯、聚丙烯、聚苯乙烯、工程塑料等的填充时,具有优良的阻燃性能,同时,所填充的合成材料的机械性能显著优于填充普通氢氧化镁阻燃剂。

Anovel magnesium hydroxide used as a fire retardant having (1) a strain in the <101> direction of not more than 3.0×10^(-3), (2) a crystallite size in the same direction of more than 80nm, and (3) a specific surface area (BET) of less than 20m^2/g and filling to PE, PP, PS and engineering plastics possesses an excellent fire retardance. And the synthetic materials filled with it exhibits obviousiy better mechanical properties than those filled with the common Mg(OH)_2.
